Only tried on once after purchase. The following is the description: A strap that can be used for both guitars and basses, combining fashion and stress-free functionality, has arrived. In addition to its fashionable appearance, the strap also reduces stress on the shoulders (stress-free) thanks to the cushioning material. The length can be adjusted in two places. The adjustment range is 128-170cm, so it can be used for both guitars and basses. Thick cushioning material is used for the shoulder part, significantly reducing the burden on the shoulders. Also, since stretchy material is not used, there is no feeling of sinking in. The belt part uses the same material as seatbelts, achieving high durability. There is also no "string vibration" that you feel when using a long leather strap. The strap pin holes use high-friction rubber material, improving both durability and holding power on the strap pins. ■ Length: Approximately 128-170cm ■ Width: Approximately 9m
